Amarillo police are searching for a man who they said robbed a bank Saturday afternoon.

Shortly before 3 p.m., officers responded to a bank robbery at Woodforest National Bank in Walmart, 3700 E. Interstate 40. The man entered as bank employees began to close for the day, said Lt. Martin Birkenfeld.

Birkenfeld said the man, who carried a shirt, demanded money from tellers after the last customer left. Police said the man gave tellers a note that implied he had a weapon. Employees told officers the weapon might have been rolled up in the shirt.

Employees handed an undisclosed amount of cash to the man, who ran east from the eastern door, police said.

The four employees were not injured, Birkenfeld said. The bank manager declined to comment.

Investigators dusted for fingerprints and footprints as other officers searched the area for the man.

Police are seeking a white man in his late 20s, about 6 feet tall and about 180 pounds. He was wearing sunglasses, a white flat cap and a yellow shirt, police said.
